Professional Focus

Dr. Solberg is Professor and Vice Chair of the Division of Medical Physics. He received his PhD in medical physics from UCLA in 1996, and served on the UCLA faculty until 2005. He subsequently held similar positions at the University of Texas Southwestern Medical Center and the University of Pennsylvania. He served on the boards of the American Association of Physicists in Medicine (AAPM), The American College of Medical Physicists (ACMP), the Commission on Accreditation of Medical Physics Educational Programs (CAMPEP) and the International Stereotactic Radiosurgery Society (ISRS). He is a Fellow of the AAPM, ACMP, American College of Radiology, and the American Society for Radiation Oncology.

Clinical Focus

Dr. Solberg’s clinical expertise includes stereotactic radiosurgery and stereotactic body radiation therapy, intensity modulated radiotherapy, image guided radiotherapy, and proton therapy. He was responsible for the installation of the world’s first Novalis in 1997, and the first Vero unit in the United States in 2011. At the University of Pennsylvania he led a Division of 42 physicists and 32 dosimetrists, supporting external beam therapy, brachytherapy, photodynamic therapy, and passive scattered and active scanned proton therapy techniques. He is engaged in several efforts to assess and improve quality and safety within radiation therapy.

Research Focus

Dr. Solberg’s research interests include small field dosimetry, particularly in the context of stereotactic body radiation therapy for lung cancer. He has considerable experience in Monte Carlo methods, in applications ranging from external beam treatment planning and brachytherapy to proton and ion therapy. He is also actively investigating the implication of respiratory motion in both conventional and proton radiotherapy. More recently, Dr. Solberg has engaged in supervised and unsupervised learning applications to large data problems in oncology.
